Installing iPhone 3G Battery 




Step 1 - Battery 

• Remove the two Phillips #00 screws from the dock- 
connector end of the iPhone. 




Step 2 

• Remove the metal handle from the suction cup. It's 
easier and safer to grip the suction cup's base instead 
of the metal handle. 



• Be very careful when opening the iPhone so 
that the cables under the display are not 
severed. 

• There is a rubber gasket between the silver 
front bezel and black display assembly. A bit 
offeree is required in this step to separate 
the iPhone's display assembly. 






• Use a small suction cup near the Home button to gently 
pull up the bottom portion of the iPhone's display 
assembly. 

• If the display assembly is too damaged to 



allow the suction cup to adhere, tape with a 
strong adhesive such as duct tape may be 
used.

Step 3 

• The display assembly is still connected to 
the iPhone by several cables, so don't try to 
remove it entirely just yet. 



& 



• Rotate the display assembly up until it is at an angle of 
approximately 45 degrees.

Step 4 

Continue to hold the display assembly with one hand, 
and use your other hand and a spudger to disconnect 
the black ribbon cable labeled "1." 




Steps 

• Rotate the display assembly up until it is roughly 
vertical. This will allow easier access for disconnecting 
the remaining cables. 

Use a spudger to disconnect the black ribbon cable 
labeled "2." 




Step 6 

• Some iPhone 3Gs may have the connector 
colors reversed (black plastic tab, white 
connector). Make sure you're flipping up the 
tab properly, otherwise you may damage 
the connector. 



& 



Use a spudger to flip up the white plastic tab holding 
the remaining ribbon cable in place. The white tab will 
rotate up 90 degrees, releasing the ribbon cable.

• Slide the black ribbon cable out of its connector, and 
remove the display assembly from the iPhone. 

• Note: You may find on some versions of the 
3G that the flip up plastic tab does not exist. 
In this case you would slide the ribbon cable 
towards the screen until it is removed. Upon 
assembly, you would apply pressure to the 
ribbon to insert it back into the ribbon 
"socket".

step 12 

• Remove the following 8 screws: 

• Five 2.3 mm Phillips #00 screws with partial 
threads securing the logic board to the rear panel. 

• Two 2.3 mm Phillips #00 screws with full threads 
securing the logic board and camera. 

- One 2.9 mm Phillips #00 screw from beneath the 
"Do not remove" sticker. 

• Note for re-assembly: 

• The screw that goes next to the camera (bottom 
right orange highlighted screw) also has a metal 
strip that holds the camera in place. 

• Remember to put this strip back in place before 
you insert the 2.3 mm Phillips #00 screws with full 
thread next to the camera 




Step 13 

• Use a spudger to gently pry the camera up and out of 
its housing in the rear panel. 

• The camera cannot be removed entirely yet 
because it's connected to the bottom of the 
logic board.

Step 14 



• Use a spudger to gently pry up the end of the logic 
board closest to the dock connector.

make sure all the screws securing the logic 
board have been removed.
